Geo Quest to the Guest is a platform game and a spin-off of the Geo Adventure series developed by "Balls" and published by Universal Interactive Studios. The game used the song "All Star" by Smash Mouth. "Balls" had announced a sequel to be released sometime in 2005, however this project never surfaced.

This was the second game to use the GeoBob Engine 2 after Greeny Phatom: The Revenge of Gree Guy. This game is one of many games to have it's code released as open source, after GeoBob Engine 2's release under MIT License in 2013.
